miss my sister :(

This is not the first instance that my sis didn't come home for a few days but this time I am kinda worried for reasons I don't know. Have tried to call her cellfone several times yesterday and today and even last weekend but I just can't reached her. Hope she is fine. Though we frequently argue on to some things but still I love her and care for her. I may not be that showy to her but truly I do. After all I am still after what's best for her. She just don't get it.
